The following discussion from gitlab-ce!21018 should be addressed: - [ ] @mikegreiling started a [discussion](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/21018#note_92414938): (+3 comments) > This is a change made in the EE-side due to the deploy boards requiring more specific key names. I see no reason not to backport it here to reduce conflicts. Currently the environment list uses the array index value as a `key` for the Vue for loop when we could use the environment ID or name (which should be unique) to do this more efficiently. /cc @jivanvl
